The mascot it super cute lion too. How can a project do everything so right? I was browsing some popular python libraries and they just slapped on the first image they got out of ChatGPT. It's nice to see care in the craft.
A mascot is an animal figure that represents a product or sports team. For example, the penguin named Tux is the mascot of Linux, and the mascot for the Brisbane Broncos rugby team is the horse named Buck the Bronco.
Genode is a framework that can run on many places and on higher level has its own abstractions. Lion OS is based on Microkit the framework developed by the seL4 people that will also be verified. So Lion OS/Microkit is basically the outgrowth of the original seL4 research.
On recent news, LionsOS, as of about a week ago (I got notified via their announcement maillist), includes a router/firewall scenario[0].
Do not miss Gernot Heiser's recent talk[1] at the seL4 Summit, where among other things he shows seL4 massively outperforming Linux in a web server scenario.

What is the purpose of this OS ? Can it mint Bitcoin ? Can it do fluid dynamics simulation ? Can it act as an interface to a database ? Can it host a database ? Is it interactive ? What kind of interface it presents to the user ?
That’s a rather luridly practical view that’s entirely out of sync with academia and basic research that provides tangible benefits much further down the line.
That begs the point: Each application will often run better on some OSes than on others. For example, high traffic websites usually aren't run on Windows 11.
no operating system does. That's application software you're thinking of. So no, it can't. But neither can windows, linux, macos, solaris, templeOS or any others
I'm trying to picture in my mind a person who is a fan of Rust and somehow against an OS with a formally-verified kernel no matter the language. I'm not having much success.
It's funny how people always allude to fanatical Rust developers in the most tangential threads, but they never actually turn up and demand we rewrite the entire Kernel in Rust or whatever terrible takes they're alleged to have.
Rust is supported by the [seL4 Microkit](https://docs.sel4.systems/projects/rust/), which is the core framework enabling LionsOS. LionsOS can currently run components written in Rust, and there are some WIP drivers written in Rust in the seL4 Device Development framework (judging from pull requests).
At least someone hasn't complained about it being 'unix like', always without defining what the non-unix-like OS they want would look like, or where the software to run on it would come from.
… except that Rust’s compiler has been qualified for several safety critical standards, with more to come, and has several formal verification tools as well. Amazon even has placed bounties (and paid some) for proving things about the standard library.
Rust is not as immature or evolving in the ways you imply.
Aussies were supposed to progress with Darbat.
It never happened.
Presumably named after Associate Professor John Lions[0], of A Commentary on the UNIX Operating System[1] fame.

It is https://www.youtube.com/watch?v=W8Ka_8kHTj4&t=903s
It's developed by UNSW Sydney, whose mascot is a Lion. (Specifically, "Clancy the Lion"), so I am guessing it's probably that.
That's also where John Lions taught.
What does mascot mean
A mascot is an animal figure that represents a product or sports team. For example, the penguin named Tux is the mascot of Linux, and the mascot for the Brisbane Broncos rugby team is the horse named Buck the Bronco.
Mascot is, unrelatedly, also a suburb of Sydney.
Not presumably, but explicitly. Both in documentation and presentations by seL4 they consistently make a point to mention so.
aka the Lions book
Very cool! I’m a huge fan of Genode, another OS that runs on SeL4. Does anyone here know how they compare?
Genode is a framework that can run on many places and on higher level has its own abstractions. Lion OS is based on Microkit the framework developed by the seL4 people that will also be verified. So Lion OS/Microkit is basically the outgrowth of the original seL4 research.

Mountain Lion is calling and wants its name back.
You mean OS X 10.7 Lion?

One application would be safety and security critical real-time systems that also need significant amount of processing power

Those are applications, not operating systems. With occasional exceptions, you can run any application on any operating system.
That begs the point: Each application will often run better on some OSes than on others. For example, high traffic websites usually aren't run on Windows 11.
There is an example of interface in the docs: https://lionsos.org/docs/examples/kitty/

Could have been done for fun. You wouldn't understand.
Yeah, Linus, what's the point?
Hardly a fair comparison. Linus wanted an OS that would run on his own PC and let him do his Unix homework assignments.
Oh no, it's written in C and not Rust. The blasphemy!

I see you have not met a lot of Rust activists.
Certainly I don't seem to run into as many of them as I'm led to believe exists.

Rust, an immature language with fluidly evolving specification / reference implementation, is not suitable for high assurance nor formal verification.
